traitSequencing[-S] extends AnyRef

Typeclass that enables for sequencing certain contain syntax in the ScalaTest matchers DSL.

An Sequencing[A] provides access to the "sequenching nature" of type A in such
a way that relevant contain matcher syntax can be used with type A. An A
can be any type of sequencing—an object that in some way brings together other objects in order.
ScalaTest provides implicit implementations for several types out of the box in the
Sequencing companion object:

scala.collection.GenSeq

scala.collection.SortedSet

scala.collection.SortedMap

Array

java.util.List

java.util.SortedSet

java.util.SortedMap

String

The contain syntax enabled by this trait is:

result should contain inOrder (1, 2, 3)

result should contain inOrderOnly (1, 2, 3)

result should contain theSameElementsInOrderAs List(1, 2, 3)

You can enable the contain matcher syntax enabled by Sequencing on your own
type U by defining an Sequencing[U] for the type and making it available implicitly.
